11 a.m.: Police have the upper hand in numbers, a reversal from Sunday morning. Many officers in riot gear are blocking the approach to the justice center's rear entrance on Southwest Second Avenue. Officers are jamming the sidewalk, making it impassible.

Protesters seem eager for access to the justice center, where the arrested man was taken.

More officers are gathered at Southwest Third Avenue and Main Street, while a group of vocal protesters remain at Fourth Avenue and Main Street.

10:51 a.m.: Tensions flare. Occupiers and a reporter from KATU get in a shouting match reportedly after a reporter asked about drug use in the camps.

10:50 a.m.: Police arrested Kevin Workman after they say he jumped over a chain at the end of Chapman Square into an area filled with tent debris. Police had told protesters not to enter the area. Workman jumped over and back and was arrested.

Wilson/The OregonianPortland police escort a handcuffed man from the area of Occupy Portland after an arrest Sunday morning.10:47: The Occupy Portland protest has sparked back to life at Chapman Square, with people mostly just chanting. One man has been arrested, however.

10:45 a.m.: Lownsdale Square is completely cleared, and crews have moved in to clean up.

But about 50 holdouts in two groups remain in Chapman Square, a few wearing gas masks on top of their heads. One group is clustered in the park's northwest corner, another in the kitchen area.

A man appeared to be trying to provoke police to arrest him.

Police, however, were maintaining a non-confrontational stance. "You could not make this up," one said as he watched.

10:15 a.m.: On the west part of Chapman Square, 25-year-old Justin Craig untied knots from tarp lines and pulled down tents. Craig hadn’t stayed at Occupy Portland but came by this morning to volunteer.

Police gave him a pair of black gloves and he got to work, and only one formation of tents remained in Craig’s area.

“For once in my life, I want to do something good and not bad,” said Craig, who acknowledged previous run-ins with the law. “It feels good to actually be helping for once.”

On the other side of Chapman, in the eastern quadrant, a woman in white pants raked leaves in the open field. And on the north side, only two structures remained. Under a canopy there, 23-year-old Kaleb Lilienthal – who has been at Occupy Portland since the outset — vowed to stay with friends unless police “physically make us” leave. When asked why they would stay when so many had gone, he said: “That’s their fault. They obviously didn’t believe strong enough.”

Across Main Street, in Lownsdale Square, nearly every tent had been removed. One Parks Bureau employee, standing near police and cleanup crews, was heard saying, “This is amazing what it looks like compared to yesterday.”

But a few feet away, 32-year-old Charles Stubbs stood in disbelief. Stubbs had set up camp near the library tent in Lownsdale but left Saturday night to avoid confrontation at the urging of his girlfriend.

There is "a fair amount of damage," said Mike Abbate, parks director. He said crews will shut down the park to let them better assess the damage. Many in the community have already offered to help repair the parks, he said.

One camper had earlier called to the others to "occupy bravo camp," the name of the encampment at Chapman Square, but few heeded. Many seemed resigned to leaving.

Some said they would wait to see what the general assembly decides at a noon meeting.

The surge of public support on Saturday night and early Sunday was heartening, said Chadd Franck. "We'd been totally depressed," he said, as campers moved out Friday and Saturday. "There was so much happening last night. ... I think the public is kind of getting the point."

10:05 a.m.: Madison Dines, 25, said he was surprised to see police officers dismantling the camp. The movement dwindled this morning and no longer had enough people to resist.

"We don't have enough physical bodies to stop the police from what they are doing," he said. "We all declared victory and went home, but the reality is we needed to be here."

10 a.m.: Juliane Dunn and her husband, Christopher, were told by a police officer shortly before 9:30 a.m. to immediately claim anything from their tent that they wanted. The couple had been at the camp in a tent near Southwest Third Avenue and Salmon Street since Oct. 6, when the occupation began.

10 a.m.: A police officer found a small tent near Southwest Salmon Street and Fourth Avenue with someone inside who said his name was Bruce. The officer shook the tent, telling Bruce the camp was closed and that he was among the last to leave.

The officer told him anything he wanted to keep, he'd have to claim; anything left would be cleared.

The officer then walked back to a group of officers and cleanup crews and said, "He's going to need some time."
